 (i) the patents and patent applications set forth in Schedule A hereto (the “Patents”);

 (ii) the trademark and service mark registrations and applications set forth in Schedule B hereto
(provided that no security interest shall be granted in United States intent-to-use trademark applications to the extent that, and solely during the period in which, the grant of a security interest therein would impair the validity or
enforceability of such intent-to-use trademark applications under applicable federal law), together with the goodwill symbolized thereby (the “Trademarks”); 
 (iii) all copyrights, whether registered or unregistered, now owned or hereafter acquired by such Grantor, including, without

 (v) any and all claims for damages and injunctive relief
for past, present and future infringement, dilution, misappropriation, violation, misuse or breach with respect to any of the foregoing, with the right, but not the obligation, to sue for and collect, or otherwise recover, such damages; and
